Description
Code to produce figures for article: Skiba, V., Jouvet, G., Marwan, N., Spötl, C., and Fohlmeister, J. (2023) Speleothem growth and stable carbon isotopes as proxies of the presence and thermodynamical state of glaciers compared to modelled glacier evolution in the Alps. Quaternary Science Reviews, 322, 108403.
This code is used to compare speleothem data with previously published glacier evolution model results (Seguinot et al., 2018; Jouvet et al., 2023) using the Parallel Ice Sheet Model (PISM, Bueler and Brown, 2009, Winkelmann et al., 2011, https://www.pism.io/)
Most speleothem data is publicly available and should be extracted from the SISALv2 database (Atsawawaranunt et al., 2018, Comas-Bru et al., 2020, https://researchdata.reading.ac.uk/256/). Previously unpublished data obtained from stalagite M6_1_57 from Schratten cave, Melchsee-Frutt cave system, Switzerland, can be found in the Supplementary material of the corresponding publication.
Alpine Ice Field simulation results are available on zenodo (https://zenodo.org/record/1423176 for Seguinot et al., 2018, and https://zenodo.org/records/8270674 for Jouvet et al., 2023).
